Cheating

Key principles of sport include that the result should not be predetermined, and that both sides should have equal opportunity to win. Rules are in place to ensure fair play, but participants can break these rules in order to gain advantage.

Participants may cheat in order to unfairly increase their chance of winning, or in order to achieve other advantages such as financial gains. The widespread existence of gambling on the results of sports fixtures creates a motivation for match fixing, where a participant or participants deliberately work to ensure a given outcome rather than simply playing to win.

Technology plays an important part in modern sport. With it being a necessary part of some sports (such as motorsport), it is used in others to improve performance. Some sports also use it to allow off-field decision making.

Sports science is a widespread academic discipline, and can be applied to areas including athlete performance, such as the use of video analysis to fine-tune technique, or to equipment, such as improved running shoes or competitive swimwear. Sports engineering emerged as a discipline in 1998 with an increasing focus not just on materials design but also the use of technology in sport, from analytics and big data to wearable technology. In order to control the impact of technology on fair play, governing bodies frequently have specific rules that are set to control the impact of technical advantage between participants. For example, in 2010, full-body, non-textile swimsuits were banned by FINA, as they were enhancing swimmers' performances.

The increase in technology has also allowed many decisions in sports matches to be taken, or reviewed, off-field, with another official using instant replays to make decisions. In some sports, players can now challenge decisions made by officials. In Association football, goal-line technology makes decisions on whether a ball has crossed the goal line or not. The technology is not compulsory, but was used in the 2014 FIFA World Cup in Brazil, and the 2015 FIFA Women's World Cup in Canada, as well as in the Premier League from 2013–14, and the Bundesliga from 2015–16. In the NFL, a referee can ask for a review from the replay booth, or a head coach can issue a challenge to review the play using replays. The final decision rests with the referee. A video referee (commonly known as a Television Match Official or TMO) can also use replays to help decision-making in rugby (both league and union). In international cricket, an umpire can ask the Third umpire for a decision, and the third umpire makes the final decision. Since 2008, a decision review system for players to review decisions has been introduced and used in ICC-run tournaments, and optionally in other matches. Depending on the host broadcaster, a number of different technologies are used during an umpire or player review, including instant replays, Hawk-Eye, Hot Spot and Real Time Snickometer. Hawk-Eye is also used in tennis to challenge umpiring decisions.
